IR-BASED CATALYST IMPROVED IN NOx REDUCTION PERFORMANCE BY H2 TREATMENT, NOx REDUCTION APPARATUS AND REDUCTION METHOD USING IR-BASED CATALYST IMPROVED IN NOx REDUCTION PERFORMANCE BY H2 TREATMENT
An object of the present invention is to solve the problem that the nitrogen oxide reduction performance is deteriorated in the process of lowering after the internal temperature of the internal combustion engine rises. In addition, another object of the present invention is to prevent the need to separately regenerate the catalyst during the operation of the internal combustion engine.The Ir-based catalyst with improved nitrogen oxide reduction performance by H 2 treatment according to the present invention is a catalyst that reduces nitrogen oxides (NOx) by using carbon monoxide (CO) in exhaust gas as a reducing agent, and is moistened by supporting ruthenium and iridium on a support. After firing in air, it is characterized in that H 2 gas is passed through.展开▼
